We have that

[√(2x+1)]+3=0
for x=4
[√(2*4+1)]+3=0
[√(9)]+3=0
3+3=0----------6 is not zero
therefore
the solution is not correct for x=4


[√(2x+1)]+3=0--------> [√(2x+1)]=-3---------> <span>There is no real solution for that equation
</span>Because (2x+1) >= 0
the solution is with complex numbers

A number is 75% of 85
sleet_krkn [62]

If a number is 75% of 85, the value of the number is 63.75.

<h3>What is 75% of 85?</h3>

Let the number the represented by 'x'

Such that; 75% of 85 = x

Solve for x.

75% of 85 = x

75% × 85 = x

75/100 × 85 = x

x = ( 75 × 85 )/100

x = 6375/100

x = 63.75

Therefore, if a number is 75% of 85, the value of the number is 63.75.

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points
shusha [124]

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left. Then  net force acting on the box IS 65N

<h3>What is net force?</h3>

Net force is final force acting on any object .

Here given that

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left

So we can see it in diagram that force in upper direction and lower direction is same 100N so this force will be cancelled out

Now force in right side is 75N and in left side force is 10N

So net force = (75-10)=65N in right side

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left. Then  net force acting on the box IS 65N
